Stoneybrook has gone star-crazy! Derek Masters, an eight-year-old regular on a hit TV sitcom, has moved to town. Everyone's wondering what a real-live TV star will be like— will he drive to school in a limo?
Jessi can't believe it, but even stars need baby-sitters,and she's the lucky club member to watch Derek Masters. Even though a lot of kids at school call Derek a spoiled brat, Jessi likes him immediately.He rides bikes and eats junk food like a normal kid, but he has exciting stories about Hollywood, too! Pretty soon baby-sitting and ballet are starting to look kind of boring next to TV scripts and cameras. Maybe Jessi would like to be a star, too!
